An Airbnb revenue forecast is a month-by-month projection of occupancy, ADR and revenue for one property, set beside comparable listings. Buyers use it to test a purchase, operators use it to check an arbitrage lease, and hosts use it to set targets for a live listing.
What I plan around in Lille: Braderie de Lille flea market; Eurostar and cross-border travel; Lille Christmas market; Flemish estaminet culture. Guests I price for: weekend and cross-border visitors on 1 to 3 night stays in Vieux Lille around the Grand Place. Where I start: the single huge Braderie weekend, Eurostar-driven short breaks from London and Brussels, and French registration numbers for city lets.
I set up PriceLabs or Wheelhouse with you so September and December weekends are loaded as events, weekday business demand has its own rules, and Booking.com and Vrbo show the same total as Airbnb, helping London and Brussels guests trust the price.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Lille.
